Clenbuterol - "A substituted phenylaminoethanol that has beta-2 adrenomimetic properties at very low doses. It is used as a bronchodilator in asthma." Medical Dictionary

Clenbuterol is classified as a beta-2 adrenergic agonist. Clenbuterol is a bronchiodilator. This drug is banned by the FDA although it is used outside the US by asthma patients. The reason although it is fairly anabolic, and it promotes the burning of fatty acids through brown fat burning. Clenbuterol is a little scary because of some other side effects including the following: tremors, sweating, sleeplessness, rapid heartbeat, etc. These side effects vary in people. Some people aren`t affected at all.

HOW DOES IT WORK

?Clenbuterol works the same way as ephedrine. However, unlike ephedrine, which is out of the body in a few hours, clenbuterol lasts for days. So you are on it 24 hours a day. No one chooses to be on ephedrine 24 hours per day, because it interferes with sleep, and so clenbuterol is more effective? says Bill Roberts (Bill Roberts holds a bachelor's degree in Microbiology and Cell Science, and a doctoral degree (Ph.D.) in Medicinal Chemistry)

Clenbuterol does work effectively as a fat burner though. It does this by slight increases in the body temperature. With each degree that the temperature in your body is raised from the use of clenbuterol, you will burn up approximately an extra 5% of maintenance calories. This makes it effective as a fat burner. Your body will fight this by cutting down on the amount of active thyroid in the body as well as through beta receptor down regulation which explains why you only have a limited effective period to take clenbuterol.

SIDE EFFECTS

The possible side effects of clenbuterol include those of other CNS(central nervous system) stimulants, and include such occurrences as shaky hands, insomnia, sweating, increased blood pressure and nausea. These side effects will generally subside after a week or so of use however, once the user becomes accustomed to the drug. Another thing people should be aware of is the inherent liver toxicity associated with clenbuterol use. When stacking with oral 17-alpha-alkylated steroids, accutane, anti-biotics or other hepatoxic elements, one should have his liver values checked by a licensed physician at regular points in time to avoid all problems. If you not a yellow discoloration of the skin cease use immediately and contact your doctor.

Caution is advised when employing the use of Clenbuterol in conjunction with other adrenoceptor agonists as side effects are likely to be cumulative. It is for this reason that it is generally not recommended to use ephedrine/ephedra (or ma huang) or the ECA stack (ephedrine-caffeine-aspirin) whilst using clenbuterol. In view of the above side effects, it is obvious to assume that anyone with cardiac issues and/or hypertension should not use a stimulant such as Clenbuterol and caution must be observed by those already using similar compounds in the treatment of existing medical conditions. In addition, there is very little conclusive knowledge of the cardiac effects of supra-physiological dosages in humans.

USAGE

It is well known that Clenbuterol use results in rapid down-regulation of beta 2 receptors. This is due to the powerful stimulatory effect of the drug. It is therefore pointless to use clen for long periods without a break. Some believe that a two day on, two day off dosing schedule will allow adequate potential for receptor up-regulation. However, I doubt this to be the case due to the relatively long half life of clen, resulting in continued stimulation even throughout the 'off' days. A much better regime would be a two week on, two week off cycle. Maximum plasma levels are reached around 2-3 hours after oral administration, and terminal half life at 34 hours (Zimmer, 1976).

It is recommended to start by taking one 20mcg tablet on the first day and then increase the dosage on the subsequent days by one tablet until the needed dosage is reached. For fat loss, clenbuterol seems to stay effective for 3-6 weeks, then it's thermogenic properties seem to subside.

There are many theories on what is the best schedule: a two week on, two week off, or one week on, one week off. 24HOURMEDSTORE.COM suggests you to find out what works best for you through experiencing.

Before starting new cycle you must wait at least for two months.

You also must be very well hydrated.

WILL CLENBUTEROL HELP ME BURN FAT?
DIET AND CARDIO are MOST IMPORTANT in this process! If one sits all the day in front of TV eating all he wants, effectiveness of Clenbuterol will be GREATLY reduced! So, training, diet, cardio and supplements should be ?taken? together. Do not try to use short cuts because they do not work!
